Supernatural (season 2)

Season two of Supernatural, an American paranormal drama television series created by Eric Kripke, premiered on September 28, 2006, and concluded on May 17, 2007, airing 22 episodes. The season focuses on protagonists Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) as they track down Azazel, the demon responsible for the deaths of their mother Mary and father John. They attempt to discover the demon's plan for Sam and other psychic children—young adults who were visited by Azazel as infants and given abilities, and whose mothers often then died in a fire. During their travels, they use their father's journal to help them carry on the family business—saving people and hunting supernatural creatures.

The season aired on Thursdays at 9:00 pm ET in the United States, and was the first season to air on The CW television network, a joint venture of The WB and UPN. The previous season was broadcast on The WB. It averaged only about 3.14 million American viewers, and was in danger of not being renewed. The cast and crew garnered many award nominations, but the episodes received mixed reviews from critics. While both the brotherly chemistry between the lead actors and the decision to finish the main storyline were praised, the formulaic structure of the episodes was criticized.
